OpenAPI definiert die folgenden Sicherheitsschemas:

* `apiKey`: ein anwendungsspezifischer Schlüssel, der stammen kann von:
    * Einem Query-Parameter.
    * Einem Header.
    * Einem Cookie.
* `http`: Standard-HTTP-Authentifizierungssysteme, einschließlich:
    * `bearer`: ein Header `Authorization` mit dem Wert `Bearer ` plus einem Token. Dies wird von OAuth2 geerbt.

OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.
* `http`: standard HTTP authentication systems, including:
    * `bearer`: a header `Authorization` with a value of `Bearer ` plus a token. This is inherited from OAuth2.

// newProgressMessage - creates new Progress Message. S3 periodically sends this message, if requested.
// It contains information about the progress of a query that has started but has not yet completed.
//
// Header specification:
// Progress messages contain three headers, as follows:

En este ejemplo, los mensajes se escribirán en el archivo `log.txt` *después* de que se envíe el response.

Si hay un query en el request, se escribirá en el log en una tarea en segundo plano.

Y luego otra tarea en segundo plano generada en la *path operation function* escribirá un mensaje usando el parámetro de path `email`.

	// Consequently, if err != nil, reply is always false
	_, err := l.ll.RUnlock(context.Background(), *args)
	return l.makeResp(resp, err)
}

// ForceUnlockHandler - query expired lock status.
func (l *lockRESTServer) ForceUnlockHandler(args *dsync.LockArgs) (*dsync.LockResp, *grid.RemoteErr) {
	resp := lockRPCForceUnlock.NewResponse()

	_, err := l.ll.ForceUnlock(context.Background(), *args)

### `Depends` 불러오기

### "의존자"에 의존성 명시하기

*경로 작동 함수*의 매개변수로 `Body`, `Query` 등을 사용하는 방식과 같이 새로운 매개변수로 `Depends`를 사용합니다:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

비록 `Body`, `Query` 등을 사용하는 것과 같은 방식으로 여러분의 함수의 매개변수에 있는 `Depends`를 사용하지만, `Depends`는 약간 다르게 작동합니다.

`Depends`에 단일 매개변수만 전달했습니다.

이 매개변수는 함수같은 것이어야 합니다.

Porém ao utilizar `Security` no lugar de `Depends`, o **FastAPI** saberá que ele pode declarar escopos de segurança, utilizá-los internamente, e documentar a API com o OpenAPI.

Mas quando você importa `Query`, `Path`, `Depends`, `Security` entre outros de `fastapi`, eles são na verdade funções que retornam classes especiais.
